did it ever print ?
if not you still have some packing in there somewhere that is blocking the print head or tape on the cartridges
if it did print but stopped you are either out of ink ( regardless of what it says )
or the print head is clogged.
There should be a print cleaning routine in the same place as the alignment on the printer menu. under maintenance or settings or ink or tools.
do that 2 or 3 times and see if it helps.
